  is 
  distinctly 
  more 
  elongate 
  and 
  shows 
  a 
  fourth 
  hyaline 
  spot 
  before 
  its 
  upper 
  apical 
  

   angle, 
  a 
  little 
  smaller 
  than 
  the 
  three 
  others, 
  which 
  are 
  disposed 
  in 
  a 
  triangle 
  ; 
  the 
  

   basal 
  hvaline 
  spot 
  of 
  the 
  third 
  posterior 
  cell 
  is 
  broadly 
  separated 
  from 
  that 
  of 
  the 
  

   axillary 
  lobe, 
  which 
  shows 
  two 
  small 
  hyaline 
  dots 
  in 
  the 
  dark 
  space 
  below 
  the 
  sixth 
  

   vein. 
  Alula 
  whitish 
  hyaline 
  and 
  unspotted. 
  The 
  costal 
  bristle 
  is 
  long 
  and 
  black. 
  

  

  Type 
  ?, 
  a 
  single 
  specimen 
  from 
  N. 
  Nigeria, 
  Zungeru, 
  15.ix.1910 
  (Br.

  The 
  character 
  of 
  the 
  long 
  and 
  decussate 
  a. 
  set. 
  is 
  common 
  to 
  the 
  present 
  species 
  

   and 
  semiatra, 
  Loew, 
  and 
  is 
  in 
  contrast 
  with 
  the 
  other 
  species 
  in 
  which 
  these 
  bristles 
  

   are 
  rudimentary 
  or 
  even 
  wanting 
  ; 
  in 
  Lamproxyna 
  there 
  are 
  likewise 
  only 
  two 
  

   set., 
  the 
  apical 
  ones 
  being 
  wanting. 
  This 
  character 
  must 
  also 
  be 
  taken 
  with 
  

   caution 
  in 
  my 
  table 
  of 
  genera 
  ; 
  even 
  the 
  character 
  of 
  the 
  i. 
  or. 
  can 
  be 
  misleading, 
  

   as 
  in 
  the 
  present 
  species 
  there 
  are 
  three 
  pairs 
  of 
  these 
  bristles, 
  while 
  the 
  other 
  

   species 
  have 
  only 
  two 
  pairs.

  A 
  robust 
  species 
  of 
  comparatively 
  large 
  size, 
  very 
  near 
  planifrons, 
  Loew, 
  but 
  

   at 
  once 
  distinguishable 
  by 
  the 
  presence 
  of 
  a 
  pair 
  only 
  of 
  scutellar 
  bristles 
  (agreeing 
  

   in 
  this 
  with 
  the 
  nearly 
  allied 
  megacephala, 
  Loew), 
  by 
  the 
  striking 
  abdominal 
  

   coloration 
  and 
  by 
  the 
  somewhat 
  different 
  wing 
  pattern.

   third 
  antennal 
  joint. 
  Eyes 
  rounded. 
  Antennae 
  inserted 
  a 
  little 
  above 
  the

   of 
  the
